Plz dont leave your home, why should you upheave your kids, esp since one attends school. This is your home, why should you go back to your parents? He can’t force you to leave.
The whole purpose of a separation is to give time to think things through n calm down but if he is willing to get up n leave n go to pakistan without considering his kids then I don’t think he is willing to try. If if there are issues between the parents, I don’t c why the kids should suffer the lose by being separated from one parent, at the end of the day he is their father n he should know his responsibilities. To me the father is the fun parent.
